[SECURITY] [DLA 2062-1] sa-exim security update



-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512

Package        : sa-exim
Version        : 4.2.1-14+deb8u1
CVE ID         : CVE-2019-19920
Debian Bug     : 946829

It was found that sa-exim, the SpamAssassin filter for Exim, allows
attackers to execute arbitrary code if users are allowed to run custom
rules. A similar issue was fixed in spamassassin, CVE-2018-11805, which
caused a functional regression in sa-exim. This update restores the
compatibility between spamassassin and sa-exim. The security
implications of sa-exim's greylisting function are also documented in
/usr/share/doc/sa-exim/README.greylisting.gz.

For Debian 8 "Jessie", this problem has been fixed in version
4.2.1-14+deb8u1.

We recommend that you upgrade your sa-exim packages.
